Subject: [PATCH] xtensa: fix signedness of gas relocations
|
|
|
|
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
|
|
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
|
|
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
|
|
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
|
|
directive. Revert this part and add test.

|
2016-02-03 Max Filippov <jcmvbkbc@gmail.com>
|
|
* config/tc-xtensa.c (md_apply_fix): Mark BFD_RELOC_XTENSA_DIFF*
|
|
substitutions for BFD_RELOC_* as unsigned.
|
|
* gas/testsuite/gas/xtensa/all.exp: Add loc to list of xtensa
|
|
tests.
|
|
* gas/testsuite/gas/xtensa/loc.d: New file: loc test result
|
|
patterns.
|
|
* gas/testsuite/gas/xtensa/loc.s: New file: loc test.
